Crash on DynamicBranchState::PrepareState(unsigned long, keywords::LocalKeywordState const&) when Shader Prewarm occurs

--

-

Reproduction steps:
1. Open the attached “ASDQWE” project
2. Open the “Assets/MainScene.unity” Scene
3. Enter the Play Mode and wait for up to 10 seconds
4. Observe the Editor

Expected result: The Editor does not crash
Actual result: The Editor crashes

Reproducible with: 2022.3.27f1
Not reproducible with: 2022.3.47f1, 6000.0.20f1
Could not test with: 2021.3.44f1 (Project contains multiple package dependencies that can not be downgraded)
Fixed in: 2022.3.28f1

Reproducible on: MacOS 14.6.1 (Intel), 14.7 (M1 (user’s))
Not reproducible on: No other environment tested

Workaround: Disable the Shader Prewarm
